FIELD

Embodiments of the present disclosure relate to the field of neural network model application, for example, to a neural network model conversion method, a neural network model conversion apparatus, a server, and a storage medium.

BACKGROUND

With the continuous maturity of deep learning technology, the application fields of neural network models are also expanding. Due to the high computational complexity of deep learning algorithms, computation devices (chips) cannot meet the requirements of many scenarios. To address this problem, more and more special inference chips for deep learning has been introduced in industry.

However, most inference chips are still based on the conventional instruction set architecture in which the operator granularity is at a tensor operator level, resulting in a low computation efficiency, and insufficient computation power for supporting various application scenarios, and limited optimization for customization of deep learning-related computation.

The customized streaming architecture breaks the limitations of the conventional instruction set architecture, and has been deeply optimized for the deep learning computation framework. In the streaming architecture, a minimum computation resolution at a basic layer operator level of deep learning is defined instead of the general instruction set. A granularity of the basic operators is larger than those of the conventional instruction set architecture, which contributes to a higher computation efficiency. However, if an algorithm trained under the instruction set architecture is to be deployed under the streaming architecture, there will be a problem of mismatching between the operator granularities of the two architectures, so additional processing is required.

As shown in FIG. 1, the neural network model conversion method according to the first embodiment of the present disclosure includes the following operations: S110, S120, S130 and S140.

S110: parsing a neural network model to obtain initial model information.

In the present embodiments, the neural network model is a complex network system formed by a large number of simple processing units (also referred to as neurons) extensively interconnected, which reflects many basic features of human brain functions and is a highly complex nonlinear dynamic learning system. In the field of neural network model application, the simple processing units of the neural network model are referred to as operators, and the neural network model is also referred to as a deep learning framework. The neural network model was usually developed based on a chip of an instruction set architecture, such as TensorFlow, Caffe, Maxnet, Torch, and etc.

Parsing a neural network model to obtain initial model information is to decompose a neural network model, and to extract a large number of first operators, connection relationships among the first operators and computation parameters of the corresponding first operators included in the neural network model. The initial model information includes an initial computation graph and initial model data, the initial computation graph includes types of the first operators and the connection relationships among the first operators, and the initial model data includes the computation parameters of the corresponding first operators.

S120: reconstructing the initial model information to obtain streaming model information.

In the present embodiments, the initial model information is obtained by parsing the neural network model, and the neural network model was developed based on the instruction set architecture, so the initial computation graph and the initial model data included in the initial model information are still an instruction set computation graph and data corresponding to the instruction set computation graph. Reconstructing the initial model information is to fuse and optimize the first operators under the instruction set architecture, and convert the first operators under the instruction set architecture into second operators under a streaming architecture, and thus, the initial model information can be converted to streaming model information. The streaming model information includes a streaming computation graph and streaming model data, the streaming computation graph includes types of the second operators and connection relationships among the second operators, and the streaming model data includes computation parameters of the corresponding second operators.

S130: generating a target model information file according to the streaming model information.

In the present embodiments, the target model information file is a file that stores neural network model information under a target streaming architecture, and the target model information file is a file that can be moved or copied, and can be saved in a specified folder. The target model information file includes a target model structure description file and a target model data file. The target model structure description file contains all content in the streaming computation graph, and the target model data file contains all content in the streaming model data.

S140: running, under a target streaming architecture, the neural network model according to the target model information file.

In the present embodiments, the target model information file is a file that can be moved or copied. By moving or copying the target model information file to a chip based on a target streaming architecture, the neural network model developed based on the instruction set architecture can be deployed to be in the chip developed based on the streaming architecture for running, which improves the computation efficiency of the neural network model.

The neural network model conversion method according to the first embodiment of the present disclosure may be implemented on a same device, or may be implemented on different devices. As an example, operations S110 to S130 can be implemented on any device containing a central processing unit (CPU) or a graphics processing unit (GPU), such as a personal computer, a server and the like; and the operation S140 may be implemented on a device with streaming architecture, such as a chip, a board card and the like.

Second Embodiment

FIG. 2 is another schematic flowchart of a neural network model conversion method according to a second embodiment of the present disclosure. The second embodiment of the present disclosure is described based on the foregoing embodiments. As shown in FIG. 2, the method may include operations: S210, S220, S230, S240, S250, S260, S270 and S280.

S210: parsing a neural network model to obtain an initial computation graph and initial model data.

In the present embodiments, parsing a neural network model is to decompose a neural network model, and extract a large number of first operators, connection relationships among the first operators, and computation parameters of the corresponding first operators included in the neural network model. The initial computation graph includes types of the first operators and the connection relationships among the first operators, and the initial model data includes the computation parameters of the corresponding first operators.

For example, the types of the first operators included in the initial computation graph are A1, A2, A3, and A4. The connection relationships among the first operators may be running A1+A2 first, and then running A1+A2+A3+A4. If a value on which A1 depends is 1, a value on which A2 depends is 2, a value on which A3 depends is 3, and a value on which A4 depends is 4, the initial model data includes 1, 2, 3, and 4.

S220: reconstructing the initial computation graph to obtain a streaming computation graph.

In the present embodiments, the streaming computation graph includes types of the second operators and connection relationships among the second operators, and the reconstructing the initial computation graph includes fusing and optimizing the first operators in the initial computation graph, to obtain the types of the second operators and the connection relationships among the second operators of the streaming computation graph. For example, the types of the first operators included in the initial computation graph are A1, A2, A3, and A4. The connection relationships among the first operators can be running A1+A2 first, then running A1+A2+A3+A4. A1+A2 is fused into B1, and A3+A4 is fused into B2, thus the types of the second operators of the streaming computation graph are B1 and B2, and the connection relationships of the second operators can be optimized as running B1 and B2 at the same time first, and then running B1+B2.

It can be known that the second operators of the streaming computation graph are formed by fusing the first operators of the initial computation graph. If the operators are represented in granularities, granularities of the second operators are larger than those of the first operators, that is, granularities of the operators under the streaming architecture are larger than those of the operators under the instruction set architecture.

S230: reconstructing the initial model data to obtain streaming model data.

In the present embodiments, the streaming model data includes computation parameters of the corresponding second operators, and the reconstructing the initial model data includes integrating and optimizing the computation parameters of the corresponding first operators in the initial computation graph. For example, the types of the first operators included in the initial computation graph are A1, A2, A3, and A4, the initial model data includes 1, 2, 3, and 4, and the initial model data in the present embodiments may further include computation result data of the first operators. A1 and A2 are fused into B1, and A3 and A4 are fused into B2, thus the types of the second operators of the streaming computation graph are B1 and B2, and streaming model data corresponding to B1 includes 1 and 2, and streaming model data corresponding to B2 includes 3 and 4. The streaming model data in the present embodiments may further include computation result data of the second operators.

Thus, the target model structure file includes that the types of the second operators are B1 and B2, and the connection relationships of the second operators can be optimized as running B1 and B2 at the same time first, and then running B1+B2.

S250: generating a target model data file according to the streaming model data.

In the present embodiments, the target model data file includes computation parameters of the corresponding second operators in the streaming model data. For example, the streaming model data includes 1 and 2, 3 and 4, and thus the target model data file includes: 1 and 2, 3 and 4, and the streaming model data in the present embodiments may further include computation result data of the second operators.

S260: constructing, under a target streaming architecture, a target streaming architecture computation graph according to the target model structure file.

In the present embodiments, constructing a target streaming architecture computation graph according to the target model structure file is to construct, in a chip based on the target streaming architecture, a streaming computation graph in conversion of the neural network model, and the chip based on the target streaming architecture provides a suitable running environment for running of the neural network model under the streaming architecture. For example, the target model structure file includes that the types of the second operators are B1 and B2, and the connection relationships of the second operators can be optimized as running B1 and B2 at the same time first, and then running B1+B2, and the target streaming architecture computation graph constructed according to the target model structure file includes that types of third operators are B1 and B2, and connection relationships of the third operators can be optimized as running B1 and B2 at the same time first, and then running B1+B2.

S270: importing the target model data file into the target streaming architecture computation graph.

In the present embodiments, when the target streaming architecture computation graph is constructed, it is equivalent that a computation framework of the neural network model in the chip based on the target streaming architecture is constructed, and when the data in the target model data file is imported into the target streaming architecture computation graph, the target streaming architecture computation graph can perform computation. For example, the target model data file includes: 1 and 2, 3 and 4, and after the data in the target model data file is imported into the target streaming architecture computation graph, data parameters of the third operator B1 are 1 and 2, and data parameters of the third operator B2 are 3 and 4, and the streaming model data in the present embodiments may further include computation result data of the second operators.
